下面是一个函数可以使用CFileDialog取得文件路径,然后用CFile打开的.

(其中,m_szEditText是已经绑定到一个CEdit里面的CString)

 CString m_szTmp;
 char buf[1000];
 CFileDialog dlg(TRUE,"mdl","*.mdl");
 if(dlg.DoModal()==IDOK) {
            CFile mfile;
             mfile.Open(dlg.GetPathName(), CFile::modeRead);
             mfile.Read(buf,sizeof(buf));
             m_szTmp = buf;
             m_szEditText = m_szTmp;
             mfile.Close();
 }
 UpdateData(FALSE);
